Hertel 72295298 Chucking Reamer 29/64 in Hss 6 Flute

Product Description

The HERTEL 72295298 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 29/64 inches (0.4531 inches decimal). It features a straight-cylindrical shank for secure chuck mounting in a drill press, lathe, or CNC machining center. With six right-hand spiral flutes and a bright uncoated finish, this reamer delivers clean, consistent hole finishes in ferrous and non-ferrous metals. Overall length is 5-5/8 inches, and the flute length measures 1-3/4 inches. Installation is performed by machinists and toolroom professionals maintaining tight bore tolerances.

This chucking reamer is suited for general machining applications where a 29/64 inch finished bore is required. It is appropriate for use in production runs, maintenance shops, and toolroom environments. The straight-cylindrical shank makes it compatible with standard drill chucks and collet-style tool holders. Right-hand cutting direction aligns with conventional spindle rotation on most machine tools. The 1-3/4 inch flute length provides adequate cutting engagement across typical workpiece thicknesses encountered in metal fabrication and repair operations.

Installation Notes

This reamer is installed and operated by machinists and tool and die professionals. Always power down and lock out the machine spindle before mounting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is properly tightened before beginning the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
